Effect of substrate salinity on the ability for protein synthesis in pea roots.

abstract：:We previously reported (A Reinero, RN Beachy 1986 Plant Mol Biol 6:291-301) that coat protein (CP) of tobacco mosaic virus (TMV) accumulates in chloroplasts of systemically infected leaves. To determine the significance of such interaction we examined electron transport rates in chloroplasts containing different level...
